Gravity vs. Mechanical Convection of Heratherm General Protocol Ovens

Gravity convection involves gentle drying and heating with low air turbulences ideal for working with materials that are sensitive to airflow such as powders and foils. These units are designed to protect delicate samples while offering temperature uniformity of ±°C with temperature stability of ±0.4°C at 150°C.

Mechanical convection is suitable for faster sample drying and heating with superior temperature uniformity of ±3.3°C with a temperature stability of ±0.3°C at 150°C.
Gravity Convection Models
  • Low turbulence gentle heating and drying of material sensitive to airflow
  • Protects delicate samples and temperature uniformity of ±3.5 °C with temperature stability of ±0.4 °C at 150 °C
  • Ideal for gentle drying applications: electronics, pharmaceutical preparations, soil, sand, powders, paper and textile
  • Ideal for curing paint adhesives, plastics and metals; vulcanization of rubber; heated storage of pills and drugs
Mechanical Convection Models
  • For fast drying of glassware, powders, paper and textile
  • Fast temperature recovery after door is opened
  • Excellent temperature uniformity of ±2.9 °C with temperature stability of ±0.3 °C at 150
